EF0 tornado, Greenville to Madison, Florida, March 31, 2020

From Greenville to Madison, this EF0 tornado ran 0.1 miles across Madison County on March 31, 2020, touching down at 4:33 PM EDT and reaching 50 yards wide. It killed nobody, and did $50,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey

9 damage points were recorded along this path by NWS TAE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 90 mph.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

A strengthening surface low pressure area moved across the Tri-State region. A warm front lifted northward through the area, and a cold front moved through during the afternoon hours. Scattered thunderstorms moved across the area, some of which were severe.

Initial damage, consisting of a few dozen trees uprooted and snapped, was noted on a farm on the west side of HWY 221 just south of I-10. Damage, consisting of hundreds of snapped and uprooted trees, continued to the east northeast crossing Sundown Creek Rd. and eventually I-10. After the tornado crossed I-10 it moved into inaccessible areas of the Hixton Swamp Conservation Area. Based on radar the tornado remained on the ground continuously until damage became accessible again along HWY 360A just south of the intersection with CR 35. Damage to several trees at this location was the last damage evident from this tornado. Damage further northeast in Madison was from a separate brief spinup after this tornado lifted. This tornado was rated EF1 with max winds estimated at 90 mph.

A business suffered roof uplift and had a window blown in. There was significant water damage inside the business. There was an outbuilding damaged at the south Duval Street location as well. There was also scattered minor tree damage in the area. This tornado was rated EF0 with max winds estimated at 75 mph. Damage cost was estimated.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:11 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
